Productivity Improvement in a Rubber-Smoked-Sheet Production Process: A Case study of the Rubber-Smoked-Sheet Plant, Promkiri Agricultural Cooperatives, Limited.
Abstract:
This research aims to study the overall process of ribbed smoked sheets production and to analyze the production efficiency of case study ribbed smoked sheets manufacturing plant as well as to identify the reasons of how ribbed smoke sheets cutting, ribbed smoked sheets bubbles and rubber waste occur during the process, including to propose operation suggestions to the case study ribbed smoked sheets manufacturing plant in order to reduce the amount of ineffective results of ribbed smoked sheets manufacturing process.
According to the data analysis on ribbed smoked sheets production of the case study plant in 2013, it is discovered that the proportion of ribbed smoked sheets production accounts for 87.40% while the amount of occurrences of ribbed smoked sheets bubbles accounts for 8.47%. Additionally, the amount of occurrences of ribbed smoked sheet cutting accounts for 4.01%, and all of which is the ineffective ribbed smoked sheets that causes the case study plant lose the income of about 190,887 baht. According to the reasons analysis, it is found that the reasons of the above problems include the following two main points: (1) the machines and related equipment are sometimes ruined; (2) the production process lacks of the operation standard. The suggestions to decrease the occurrences of ineffective rubbers include the followings: (1) to fix the rubber smoke house and the installation of temperature measuring system inside the rubber smoked house; (2) to fix the ruined rubber press machines; (3) to identify the appropriate distance between each rubber roller; (5) to change the sheet rubber hangers to the new ones; (4) to change Takong (the trays for shaping latex into the required rubber sheets) and the damaged latex tubing into the new ones; (5) to define the clear periods to maintain the sheet rubber hangers, Takong and latex tubing; (6) to identify the clear strategies as to carefully check the sheet rubber hangers; (7) to clarify the periods of exchanging the latex in the latex tubing; (8) to appoint the supervisor who will take charge of controlling the operation of rubber sheets drying and Takong cleaning process; (9) to identify the standardized ratio of latex mixtures.
According to the application of the above suggestions, it is discovered that the suggestions help increase the efficiency of 94.71% of the third level ribbed smoked sheets manufacturing, which has 7.31% increasing amount from the former process, and takes 5.29% of reduction in the ineffective results of ribbed smoked sheets production, comparing to the previous year. This can decrease the values of loss of ineffective ribbed smoked sheets production, which equals to 134,563 baht per year.
